Overcoming the slowing down of flat-histogram Monte Carlo simulations: Cluster updates and optimized broad-histogram ensembles
Monte carlo simulation energy d ferromagnetic ising model
2014/12/20
We study the performance of Monte Carlo simulations that sample a broad histogram in energy by determining the mean first-passage time to span the entire energy space of d-dimensional ferromagnetic Is...

quantum optics continuous variable cluster state feedback
2011/12/15
In this paper, we investigate the generation of continuous-variable quadripartite square cluster state of optical fields and discuss the enhancement of the multipartite entanglement of the cluster sta...

Breakup reactions are one of the main tools for the study of exotic nuclei,and in particular of their continuum. In order to get valuable information from measurements.
Analysis of a continuous-variable quadripartite cluster state from a single optical parametric oscillator
continuous-variable quadripartite cluster state single optical parametric oscillator
2010/10/20
We examine the feasibility of generating continuous-variable multipartite entanglement in an
intra-cavity quadruply concurrent downconversion scheme that has been proposed for the generation of clust...
We discuss a cluster-like 1D system with triplet interaction. We study the topological properties of this system. We find that the degeneracy depends on the topology of the system, and well protected ...
基于Cluster观测对地球磁尾电流片磁场分布的初步统计分析
Cluster 地球 磁场
2013/9/3
利用Cluster在2001~2005年期间每年6~11月4 s精度的磁场数据对磁尾电流片的磁场分布特性进行了统计分析. 结果表明, 电流片中心处磁场及其Bz分量的强度在磁尾午夜区通常较弱, 而在磁层晨、昏两侧处普遍较强, 这表明午夜区的电流片较薄, 而在晨、昏两侧的电流片较厚. 在晨昏两侧处, 电流片拍动剧烈, 尤以晨侧最甚, 而午夜区的电流片拍动最弱. 在磁地方时21:00~01:00范围内,...

We present schemes to prepare two-dimensional cluster states [H. J. Briegel and R. Raussendorf, Phys. Rev. Lett. {\bf 86}, 910 (2001)] with atomic ions confined in a micro-structured linear ion trap a...
本文分析了 2002年 9月 10日 Cluster四颗卫星穿越南极和北极极隙区期间的观测资料。
这两次穿越是在弱而稳定的南向行星际磁场 ( I MF)条件下发生的。数据显示极隙区中的场向
电流 ( FACs)引起了大的磁场扰动。本文采用了一种基于卫星多点测量来计算扰动界面方向和
运动速度的方法。结果显示界面与磁力线大致平行 , 而它们的速度在卫星穿越南极极隙区时
几乎朝向晨侧 ,在穿越北...
